RCC344, Thank you for your feedback on our smart watering system. Currently the timer is set to update overnight every 24 hours but you will always have the option to override a rain delay from your app if the forecast changes by the time you need to water.
As for the smart watering, your watering history should reflect what is actually watered, even when a rain sensor delay is triggered. Could you please provide the MAC address for your timer and I will see if there are any settings keeping this from working properly. You may replay on this forum or email at [email protected].
